[0027] As Figure 1The utility model discloses an embodiment provides a kind of lubricating system, including liquid storage pool 1, conveying assembly 2, communication pipe 3, control valve 4, processing component (not shown in drawing), input pipe 5 and first filter piece 6.Processing liquid for at least lubrication is stored in liquid storage pool 1.Conveying assembly 2 is at least provided with two, each conveying assembly 2 is communicated with liquid storage pool 1, to be able to respectively conveying processing liquid to same or different piece 11 to be handled.

[0028] Specifically, the processing liquid stored in the liquid storage pool 1 can typically be lubricating oil, and the piece 11 to be handled can be a motor or the like that needs to be lubricated with lubricating oil. The specific type of lubricating oil can be selected according to the application scenario of the lubricating system, as long as it can meet the lubrication requirements of the piece 11 to be handled. Taking the motor as the piece 11 to be handled as an example, the processing liquid can typically have the functions of cooling, anti-oxidation, rust prevention, and anti-wear, in addition to lubrication, so as to improve the operating performance of the motor and prolong the service life. To avoid contamination of the processing liquid by external impurities, a sealing structure can be provided on the liquid storage pool 1, which can be provided at the connection between each input pipe 5 and the liquid storage pool 1 or the like, so as to form a relatively closed space inside the liquid storage pool 1 and isolate the external environment.

[0029] One end of the conveying assembly 2 is communicated with the liquid storage pool 1 through the input pipe 5, and the other end is connected with the piece 11 to be handled, so as to form a channel for conveying the processing liquid between the liquid storage pool 1 and the piece 11 to be handled. In the utility model embodiment, the conveying assembly 2 is at least provided with two, and according to the number of the pieces 11 to be handled, each conveying assembly 2 can be connected with different pieces 11 to be handled, or connected with the same piece 11 to be handled, or the same conveying assembly 2 can be connected with multiple pieces 11 to be handled, and the setting mode is flexible. For example, in one embodiment, the lubricating system is applied to a vehicle having two driving pieces, and the conveying assembly 2 can be provided with two, so that each conveying assembly 2 is connected with one driving piece; or the conveying assembly 2 can be provided with four, so that each two conveying assemblies 2 are connected with one driving piece at the same time.

[0030] The connecting pipe 3 can connect at least two conveying components 2 to each other, and the number of conveying components 2 that each connecting pipe 3 can connect varies depending on the form of the connecting pipe 3. For example, when the connecting pipe 3 is a common pipe with two openings, such as Figure 1 As shown, the connecting pipe 3 can connect the two conveying components 2 to each other; and when the connecting pipe 3 is a pipe with more openings, such as a tee pipe, as... Figure 2 As shown, the connecting pipe 3 can simultaneously connect three or more conveying components 2 to each other.

[0031] The specific form of the connecting pipe 3 can be selected based on factors such as the number of conveying components 2. If necessary, multiple connecting pipes 3 can also be provided. For example, when three conveying components 2 are provided, one embodiment is as follows: Figure 2 As shown, a three-way connecting pipe 3 can be used to connect the three conveying components 2 to each other simultaneously; another implementation scheme is as follows: Figure 3 As shown, three connecting pipes 3 can be used, and each connecting pipe 3 connects the three conveying components 2 in pairs.

[0032] To control the connection and disconnection between the conveying components 2 connected to the connecting pipe 3, and to ensure that different conveying components 2 are connected to each other only when needed, this embodiment of the invention uses a control valve 4 connected to the connecting pipe 3. The control valve 4 can be configured in various ways, depending on the number of conveying components 2, the number of connecting pipes 3, and their specific form. For example, when only two conveying components 2 are provided, such as... Figure 1 As shown, if only one connecting pipe 3 is provided, then only one control valve 4 is needed, and it can be connected to the connecting pipe 3. When three conveying components 2 are provided, one embodiment is as follows: Figure 2 As shown, the connecting pipe 3 can be in the form of a tee pipe, so there can be three control valves 4. Each control valve 4 is located between the center of the tee pipe and each conveying component 2. In this design, each control valve 4 only controls the connection or disconnection of a portion of the connecting pipe 3, that is, controls the connection or disconnection between one conveying component 2 and other conveying components 2. When there are three conveying components 2 and three connecting pipes 3, one embodiment is as follows: Figure 3 As shown, each connecting pipe 3 connects the conveying components 2 in pairs. Therefore, the control valve 4 can be configured in three units corresponding to the number of connecting pipes 3, each connected to a different connecting pipe 3. Another implementation scheme is as follows... Figure 4 As shown, the control valve 4 can be in the form of a three-way valve, with three connecting pipes 3 connected to the three ports of the three-way valve respectively.

[0033] It is understandable that the arrangement of the conveying component 2, the connecting pipe 3, and the control valve 4 is not unique. The design is highly flexible and can be carried out according to the needs of the actual application scenario, referring to the examples of the above implementation schemes.

[0034] The processing assembly is a component assembly for realizing automatic control of the lubricating system. By being electrically connected with the conveying assemblies 2 and the control valve 4 respectively, the processing assembly can control the movement of the control valve 4 according to the operation of at least one of the conveying assemblies 2 and the workpiece 11, i.e., control the connection or disconnection between the conveying assemblies 2. In order to realize the electrical control of the control valve 4, the control valve 4 can generally adopt an electromagnetic valve. According to the number of channels of the control valve 4, the control valve 4 can adopt a two-position two-way electromagnetic valve, a two-position three-way electromagnetic valve, etc.

[0035] Specifically, the processing assembly can also obtain the working state of the workpiece 11. For example, for the driving part of the vehicle, the processing assembly can detect at least one parameter of the rotational speed, temperature and power of the driving part, and determine the working state of the driving part through the obtained parameter, and then determine the demand of the driving part for the processing liquid. When the demand of the driving part for the processing liquid is large, the control valve 4 can be opened to make the conveying assemblies 2 communicate with each other, so that the processing liquid conveyed by the conveying assemblies 2 can be concentrated and supplied to the driving part. Similarly, when the demand of the driving part for the processing liquid is small, the processing assembly can close the control valve 4 to make the conveying assemblies 2 work independently and not affect each other, so as to save energy and reduce the waste of the processing liquid. In addition, when part of the conveying assemblies 2 fail, the processing assembly can also open the control valve 4 to make the other normal conveying assemblies 2 replace the failed conveying assemblies 2 to convey the processing liquid, so as to meet the use demand in emergency.

[0036] On the basis of being provided with multiple conveying assemblies 2, the utility model embodiment still adopted each conveying assembly 2 is communicated with the liquid storage pool 1 through different input pipe 5, and the first filter piece 6 is connected on each input pipe 5 respectively, make the treatment liquid in the liquid storage pool 1 after the filtration of first filter piece 6, again through conveying assembly 2 is transported to the piece 11 to be handled, to improve the cleanliness of treatment liquid, enhance the lubricating property of treatment liquid, still can reduce the impurity in treatment liquid to cause the important structure such as the collision, wear and tear of control valve 4 or the component in conveying assembly 2 to some extent problem. And, because each conveying assembly 2 and corresponding input pipe 5 and first filter piece 6 jointly constitute independent conveying channel, such design compares with the design of multiple conveying assemblies 2 simultaneously through an input pipe 5 is communicated liquid storage pool 1, and each input pipe 5 only needs to be adapted to the treatment liquid flow demand of one conveying assembly 2, to be able to reduce the flow burden of single input pipe 5, satisfy the demand of liquid amount. In addition, by setting first filter piece 6 on each input pipe 5 respectively, when multiple conveying assemblies 2 simultaneously carry out conveying work, multiple first filter pieces 6 also simultaneously carry out filtering work, treatment liquid does not need to pass through the same filter piece to carry out filtration, also can reduce the blockage problem caused by the accumulation of treatment liquid impurities on the same filter piece, to improve the filtering efficiency to treatment liquid, improve the fluency of treatment liquid flow.

[0037] The lubricating system provided by the embodiment of the utility model, including liquid storage pool 1, conveying assembly 2, communication pipe 3, control valve 4, processing assembly, input pipe 5 and first filter piece 6, conveying assembly 2 is provided with at least two, and each conveying assembly 2 is communicated with liquid storage pool 1. By adopting communication pipe 3, at least two conveying assemblies 2 are communicated with each other, and control valve 4 is communicated or disconnected under the control of processing assembly, when control valve 4 is communicated, the processing liquid conveyed by multiple conveying assemblies 2 can be supplied to the same (such as the driving member of vehicle) to be treated piece 11, thereby the conveying and distribution capacity of processing liquid is greatly improved, and the risk of lubricating system failure is reduced. Meanwhile, by adopting the fact that each conveying assembly 2 is communicated with liquid storage pool 1 through different input pipes 5, and each input pipe 5 is connected with first filter piece 6, when control valve 4 is disconnected, each conveying assembly 2 can independently obtain relatively clean processing liquid from liquid storage pool 1, each conveying assembly 2 does not interfere with each other, and does not need to run or stop simultaneously, which can reduce the waste of processing liquid and energy loss, thereby the utilization rate of processing liquid and the working efficiency of lubricating system are improved. Moreover, compared with the design that multiple conveying assemblies 2 are communicated with liquid storage pool 1 through one input pipe 5, the flow burden of single input pipe 5 can be reduced, when multiple conveying assemblies 2 are conveyed simultaneously, multiple first filter pieces 6 are filtered simultaneously, the clogging problem caused by the accumulation of processing liquid impurities on the same filter piece can be reduced, thereby the filtering efficiency and conveying efficiency of processing liquid are improved.

[0038] As shown in some embodiments, Figure 1 The conveying assembly 2 includes a conveying pipe 21 and a conveying pump 22, one end of the input pipe 5 is connected to the input end of the conveying pump 22, one end of the conveying pipe 21 is connected to the output end of the conveying pump 22, and the other end of the conveying pipe 21 is connected to the to-be-processed piece 11. The communication pipe 3 is connected between at least two conveying pipes 21, so that the processing liquid pumped by the conveying pump 22 can be distributed among different conveying pipes 21 according to requirements.

[0039] Specifically, the delivery pump 22 is configured to provide a driving force for the treatment liquid to flow through the delivery pipe 21 to the workpiece 11 to be treated. The delivery pump 22 can be manually controlled or electrically controlled. When the delivery pump 22 is manually controlled, the user can control the opening or closing of the delivery pump 22 and adjust the rotating speed of the delivery pump 22 according to the actual needs. This form of delivery pump 22 has a low cost and high reliability in the case of circuit failure. When the delivery pump 22 is electrically controlled, the delivery pump 22 can be electrically connected to the processing assembly. The processing assembly can automatically control the opening or closing of the delivery pump 22 and adjust the rotating speed of the delivery pump 22 according to the working state of the workpiece 11 to be treated, so as to meet the flow demand of the workpiece 11 to be treated. This form of delivery pump 22 does not need to be manually operated and has good convenience and high intelligence. It should be understood that the forms of the delivery pumps 22 can be the same or different, which can be selected according to the actual needs.

[0040] Alternatively, when the demand of the workpiece 11 to be treated for the treatment liquid is small, the processing assembly can select to close the control valve 4, so that each delivery assembly 2 only supplies the treatment liquid to the corresponding workpiece 11 to be treated. In addition, the processing assembly can also select to close the delivery pump 22 in part of the delivery assemblies 2, so that the treatment liquid is supplied to all the workpieces 11 to be treated through part of the delivery pumps 22. Both the above-mentioned two processing modes can achieve the effect of reducing energy consumption.

[0041] In some embodiments, as shown in Figure 1 The lubrication system further comprises a throttle valve 7, which is arranged on the delivery pipe 21 and electrically connected to the processing assembly. The throttle valve 7 is configured to adjust the flow of the treatment liquid in the delivery pipe 21. The communication pipe 3 is connected to the part of the delivery pipe 21 between the delivery pump 22 and the throttle valve 7.

[0042] Specifically, the throttle valve 7 can control the flow of the treatment liquid in the delivery pipe 21 by adjusting the opening range of the valve. The action of the throttle valve 7 is controlled by the processing assembly, so that the processing assembly adjusts the flow of the treatment liquid according to the demand of the workpiece 11 to be treated for the treatment liquid. For example, as shown in Figure 1 When the demand of the workpiece 11 to be treated connected to the left delivery pipe 21 for the treatment liquid is large, the processing assembly can open the control valve 4 to make the left and right delivery pipes 21 communicate with each other through the communication pipe 3. At the same time, the processing assembly can adjust the opening range of the left throttle valve 7 to the maximum and reduce the opening range of the right throttle valve 7, so that most of the treatment liquid flows to the left workpiece 11 to be treated, thereby meeting the demand of the left workpiece 11 to be treated for the treatment liquid. In other cases, the opening range of each throttle valve 7 can be flexibly adjusted or dynamically adjusted over time, which has high adjustment flexibility and only needs to meet the actual use demand.

[0043] The above embodiment can flexibly distribute the flow of the treatment liquid in different delivery pipes 21 by adjusting the opening range of each throttle valve 7, thereby further improving the distribution capability of the treatment liquid and reducing the waste of the treatment liquid.

[0044] In some embodiments, as shown in Figure 1 The lubrication system further comprises a flow meter 8, which is arranged on the delivery pipe 21 and located between the throttle valve 7 and the to-be-treated part 11. The flow meter 8 is used to detect the flow value of the treatment liquid delivered in the delivery pipe 21.

[0045] Optionally, in some embodiments, the flow meter 8 can be electrically connected with the treatment assembly, so that the treatment assembly can monitor the flow of the treatment liquid in the delivery pipe 21 and control the action of the related components in real time according to the flow value. For example, the treatment assembly can control the throttle valve 7 to open or close the valve at a certain speed according to the difference between the current flow value and the target flow value, so that the throttle valve 7 is adjusted to a certain opening range after a preset time. Through such a setting, the treatment assembly can realize real-time monitoring of the flow of the treatment liquid in the delivery pipe 21, and can also perform more complex dynamic control operations, which has high intelligence.

[0046] Of course, it can be understood that the flow meter 8 can also not be electrically connected with the treatment assembly, but only needs to have the function of detecting the flow. For example, the flow meter 8 can only be used for the user to observe the flow of the treatment liquid in the delivery pipe 21, so that the user can intervene in the control of the treatment assembly when necessary.

[0047] In some embodiments, the treatment assembly comprises a detection part and a controller. The detection part is used to detect at least the operating parameter of the to-be-treated part 11 and generate a detection signal. The controller is electrically connected with the detection part, the throttle valve 7 and the delivery pump 22. The controller is used to receive the detection signal, control the rotating speed of the delivery pump 22, switch the control valve 4 between the opening and the closing, and adjust the opening degree of each throttle valve 7.

[0048] Optionally, in addition to detecting the operating parameter of the to-be-treated part 11, the detection part can also be used to detect the operating state of other related components, for example, the rotating speed of the delivery pump 22, the opening range of the throttle valve 7, or the detection part can also be electrically connected with the flow meter 8 to detect the flow of the treatment liquid in the delivery pipe 21 through the flow meter 8, etc. The specific detection standard can be designed according to the actual needs.

[0049] In some embodiments, as shown in Figure 1As shown, the lubrication system further comprises a second filter 9, which is arranged on the delivery pipe 21 and located between the throttle valve 7 and the to-be-processed member 11.

[0050] Specifically, the second filter 9 and the first filter 6 have the same function, i.e., both are used for filtering the passing treatment liquid to reduce impurities in the treatment liquid. The second filter 9 is further arranged on the basis of the first filter 6, which can enhance the filtering effect and improve the cleanliness of the treatment liquid.

[0051] Optionally, the first filter 6 and the second filter 9 can be the same or different in form. For example, in some embodiments, the first filter 6 can be a suction filter, and the second filter 9 can be a pressure filter. The suction filter can filter large-particle impurities in the treatment liquid to prevent the large-particle impurities from entering the delivery pipe 21 and causing collision damage to components such as the delivery pump 22. The pressure filter can further filter small-particle impurities to prevent the small-particle impurities from entering the to-be-processed member 11 and causing wear and tear problems due to the movement of the to-be-processed member 11, thereby achieving a better filtering effect. Of course, the first filter 6 and the second filter 9 can also be combined in other forms, for example, the first filter 6 can be a pressure filter, and the second filter 9 can be a suction filter, as long as the desired filtering effect can be achieved.

[0052] In some embodiments, as shown in FIG. 1, Figure 1 As shown, the lubrication system further comprises a cooler 10, which is arranged on the delivery pipe 21 and located between the second filter 9 and the to-be-processed member 11 to cool the treatment liquid after passing through the second filter 9. By arranging the cooler 10, the temperature of the treatment liquid can be reduced, so that the treatment liquid not only has a lubricating effect but also has a cooling effect, which can take out the heat generated by the to-be-processed member 11 to prevent the to-be-processed member 11 from being damaged due to high temperature during operation.

[0053] Optionally, the position where the communication pipe 3 is connected to the delivery pipe 21 can not only be connected between the delivery pump 22 and the throttle valve 7 as described in the above embodiments, but also be connected to other positions of the delivery pipe 21. For example, the communication pipe 3 can be connected between the throttle valve 7 and the second filter 9, so that the treatment liquid can be delivered through other delivery pipes 21 and the communication pipe 3 when the throttle valve 7 connected to a certain delivery pipe 21 fails, to ensure temporary use in the case of failure. Similarly, the communication pipe 3 can also be connected to other positions such as between the second filter 9 and the cooler 10, as long as the actual needs are designed, and the design flexibility is high.

[0054] The utility model embodiment further provides a vehicle, including drive piece 12 and above -mentioned lubricating system. Among them, drive piece 12 is above -mentioned to be handled piece 11, the number of drive piece 12 is set not more than the number of conveying assembly 2, and each drive piece 12 is at least communicated with one different conveying assembly 2.

[0055] Specifically, when the number of drive piece 12 is equal to the number of conveying assembly 2, each drive piece 12 can be respectively communicated with one different conveying assembly 2. When the number of drive piece 12 is less than the number of conveying assembly 2, then part drive piece 12 can be simultaneously communicated with multiple conveying assembly 2, but it needs to meet that each drive piece 12 is connected with at least one conveying assembly 2, and each conveying assembly 2 is connected with at least one drive piece 12, to ensure that the treatment liquid can be delivered to each drive piece 12.

[0056] The vehicle provided by the utility model embodiment adopts the above lubricating system to provide lubricating effect for drive piece 12, and the lubricating system can realize the cooperation between each conveying assembly 2 through the design of the above embodiment, has strong treatment liquid delivery and distribution capacity, low failure risk, can provide reliable lubricating effect for the drive piece 12 of vehicle, and the running performance of vehicle is good.

[0057] Some embodiments, as shown in Figure 1 As shown, drive piece 12 has an inlet 121 for the treatment liquid to enter and an outlet 122 for the treatment liquid inside to flow out, the inlet 121 is communicated with one end of conveying assembly 2 for outputting treatment liquid, and the outlet 122 is communicated with liquid storage pool 1. By setting in this way, the treatment liquid flowing through drive piece 12 can flow back to liquid storage pool 1, so as to realize the recycling of treatment liquid, and greatly reduce the waste of treatment liquid.

[0058] The above embodiments are only preferred embodiments for fully illustrating the utility model, and the protection scope of the utility model is not limited to this. The equivalent replacement or transformation of the technical personnel in the technical field on the basis of the utility model is all within the protection scope of the utility model.
